Sony Alpha NEX-5T vs. Sony Cyber-shot DSC-W320: In-Depth Comparison for Photographers

Selecting the right camera can be a complex puzzle, especially when brand name familiarity points to two very different models like the Sony Alpha NEX-5T and the Sony Cyber-shot DSC-W320. Although both hail from Sony, these cameras sit at almost opposite ends of the spectrum in terms of design philosophy, capabilities, and intended audiences. Having spent hundreds of hours testing and comparing digital cameras across genres, I’ll take you through a nuanced comparison exploring how these two cameras diverge - and where each truly shines.

Photographers, enthusiasts, or professionals researching next camera additions will find this head-to-head thorough yet approachable, guiding you to a properly informed purchase decision aligned with your creative ambitions and workflow.

Physical Design and Handling: First Impressions Matter

The very first tangible distinction is size and build, and here the difference is almost stark.

The Sony Alpha NEX-5T adopts the rangefinder-style mirrorless design prevalent among early Sony E-mount cameras, with dimensions of approximately 111 x 59 x 39 mm and a weight of 276g. Compared to the ultra-compact Sony W320, which measures a tiny 93 x 52 x 17 mm and weighs a feather-light 117g, the NEX-5T is larger but noticeably still pocketable for many.

Why does this matter? The NEX-5T’s larger grip and body allow for more confident handling during extended shoots or with heavier lenses attached. It's ergonomically friendlier for any serious photo hobbyist or professional who needs comfort to deliver steady shots and quick access to controls over long days. The smaller W320, while perfect for slipping into your jeans pocket or clutch bag, offers minimal grip. It is clearly designed as a highly portable, grab-and-go point-and-shoot camera.

Moving on to control layout, the top view comparison underscores the enthusiast orientation of the NEX-5T.

The NEX-5T places dedicated dials and buttons for exposure compensation, shutter speed, and complete manual control - features absent in the W320. The compact Cyber-shot keeps controls pared back, emphasizing simple auto shooting modes without any manual override. For photographers who crave tactile feedback and instant exposure adjustments, the NEX-5T undeniably offers a better platform.

Sensor and Image Quality: The Heart of Photographic Fidelity

Camera performance today pivots on sensor technology, which largely determines image quality, ISO behavior, dynamic range, and color reproduction.

The NEX-5T boasts an APS-C CMOS sensor measuring 23.4 x 15.6 mm - a substantial imaging surface area of 365mm². It holds 16 megapixels and uses Sony’s Bionz processor, facilitating 1080p full HD video and reliable autofocus performance. APS-C sensors in this size bracket offer impressive dynamic range, low noise at high ISO, and excellent color depth for keen detail and vibrant, accurate skin tones or landscape reproductions.

In contrast, the Sony W320 features a modest 1/2.3" CCD sensor just 6.17 x 4.55 mm (28mm²), with a 14-megapixel count. This sensor size is typical for ultra-compact fun cameras but is limited in light gathering capability and noise control, confining image quality especially in low light or demanding dynamic range scenarios.

Real-world testing clarifies how these specs translate: The NEX-5T’s images display cleaner, more nuanced gradation, and a broader latitude for postprocessing correction without quality loss. The W320’s JPEG images come out decent under good lighting but exhibit visible noise and color shifts as light levels drop - not unusual for a CCD sensor of this class and era.

Display and Interface: What You See Is What You Get

For framing and reviewing shots, LCD screen quality and usability matter deeply.

Here, the NEX-5T aims higher. It sports a 3-inch Tilting TFT LCD with 922k dots resolution and offers a selfie-friendly 180° tilt-up range, useful for self-portraits or high-angle shots. Critically, it features touchscreen functionality for intuitive autofocus point selection and menu navigation - a boon when rapid adjustments or creative framing are needed on the fly.

The W320 has a smaller 2.7-inch fixed LCD with a much lower 230k-dot resolution and no touchscreen. While adequate for casual framing, it’s not suited for precision review or artistic composition work. Its fixed nature can limit ergonomic comfort during awkward shooting angles.

Autofocus and Shooting Performance: Speed, Accuracy, and Tracking

A critical determinant of a camera’s versatility is how well it autofocuses, especially in genres like wildlife or sports photography.

The Sony NEX-5T employs a hybrid autofocus system combining phase-detection and contrast-detection with 99 focus points - including 25 cross-type sensors that dramatically improve focus accuracy and speed. Face detection and liveview AF assist quick, reliable tracking, and it can capture bursts at 10 frames per second. For fast-moving subjects like athletes, birds, or street performers, this combination reliably locks onto action.

Conversely, the W320 offers only simple contrast-detection autofocus with 9 points and lacks continuous AF or advanced tracking features. Its single frame shooting rate per second and absent manual exposure control highlight that this camera is positioned more as an easy snapshot device rather than a precision tool for dynamic subjects.
